Two new mechs spotted on the set of Prometheus

We don't often get very much out of Ridley Scott's secretive PROMETHEUS, so we have to make do with what little we can uncover.

The intrepid spy team over at AlienPrequelNews.com (how many of these fan sites do you think are secretly viral operations of the studio to generate buzz?) dug up these shots of some rather cool looking futuristic vehicles from the set of PROMETHEUS.

You can see both mechs below, the first being some sort of transport that reminds me a bit of the Mako from Mass Effect, and the second? I can't quite figure out what it's supposed to be. A giant loader type vehicle? Something not fully assembled? See what you make of them below:
